background & aim : mother-infant separation is one of the main causes of sleep-wake states disorders in neonatal intensive care unit (nicu). the current study was conducted to investigate the effect of in-arms-holding by mothers on sleep-wake states disorders of preterm neonates. methods & materials : in a pilot study, through a semi-experimental pretest-posttest method, 35 preterm neonates wit...

Sleep-wake schedule disorder is defined by DSM-III-R as a mismatch between the normal sleep-wake schedule for a person's environment and his or her circadian sleep-wake pattern. The authors report a case in which a sleep-wake schedule disorder arose after a closed head injury. Sleep-wake schedule disorder has not been described as an outcome of closed head injury. As patients with sleep-wake sc...

purpose: to investigate associations between computer use data and sleep quality among university students. materials and methods: this descriptive, cross-sectional study was performed on 312 students of tehran university of medical sciences, iran. data was collected using epworth sleepiness scale (ess), insomnia severity index (tsi), pittsburgh sleep quality index (psqi), and a background and ...

Blind people are prone to suffer from sleep-wake schedule disorders. This report describes 2 months of monitoring of sleep patterns and aggressive behaviors in a totally blind, severely retarded adolescent boy, hospitalized in a psychiatric hospital. The documented sleep-wake patterns seem to portray a sleep-wake schedule disorder with a monthly periodicity. Aggressive behaviors seem to echo th...

During the last decade actigraphy (activity-based monitoring) has become an essential tool in sleep research and sleep medicine. The validity, reliability and limitations of actigraphy for documenting sleep-wake patterns have been addressed. Normative data on sleep-wake patterns across development have been collected. Multiple studies have documented the adequacy of actigraphy to distinguish be...

OBJECTIVE To longitudinally examine objective and self-reported outcomes for recovery of cognition, communication, mood and participation in adults with traumatic brain injury (TBI) and co-morbid post-traumatic sleep/wake disorders. DESIGN Prospective, longitudinal, single blind outcome study. SETTING Community-based. PARTICIPANTS Ten adults with moderate-severe TBI and two adults with mi...

BACKGROUND Alteration of the intensity of light reaching the pineal gland through the visual pathway affects the sleepwake cycle in humans. OBJECTIVE To determine the prevalence, types and severity of sleep-wake disorders in the blind and their relation to the degree and cause of blindness. METHODS One hundred and seventy consecutive blind patients were included in the study. The patients w...

Several melatonin receptors agonists (ramelteon, prolonged-release melatonin, agomelatine and tasimelteon) have recently become available for the treatment of insomnia, depression and circadian rhythms sleep-wake disorders. The efficacy and safety profiles of these compounds in the treatment of the indicated disorders are reviewed. Accumulating evidence indicates that sleep-wake disorders and c...

Subcortical circuits mediating sleep-wake functions have been well characterized in animal models, and corroborated by more recent human studies. Disruptions in these circuits have been identified in hypersomnia disorders (HDs) such as narcolepsy and Kleine-Levin Syndrome, as well as in neurodegenerative disorders expressing excessive daytime sleepiness. However, the behavioral expression of sl...
